For your IA this year you can choose from one of 3 topic: 1) Serial Poitioning Effect- position of word order effects an individual's ability to rememebr items in a list 2) Memory Load Interference- the memory of a set of items is interfered with with the introduction of a second set of data 3) Stroop effect-the color a word is printed in interferes with an individuals ability to quickly process what word is being said.
Important Documents
Student guide for completing the IA
Introduction
1) Describe the original study you are replicating.
2) validate teh origianl study and your justification for replication through the use of other studies (2 SL/ 4 HL)
3) State your aim (include yoru variables)
4) State your hypothesis (SL research/ HL research and null)
Methods section
Design
1) You are conducting an experiment- How is yours different from the original you are replicating?
2) Two choices- repeated measures or independent samples
3) Justify why you chose the the design you did
4) Operationalize IV
5) Operationalize DV
Participants
1) Describe your sample with relevant information (age, grade, courses taken, gender, etc.)
2) Random or convenience sampling
3) Justify your decision
4) Random assignment- explain how you achieved this and justify
Materials
include a list of materials that you used
All materials should have an accompanying appendix
Procedures
A detailed list of the procedures you used
This should allow another person to replicate your study (ask your parents to read it and see if it makes sense)
Make sure to include ethical features (consent forms, briefing instructions, debriefing instructions all should then be in appendices)
Results section
Needs to include both a table and a graph (these should appear in your body not appendices)
Make sure they are labled
Make sure you reference them the chart and graph in your written section.
Your written section should include one measure of central tendency and one measure of dispersion
The measure will depend upon the type of data you have. justify your choice of measurement based upon your data type.
HL you need to report one inferential statistic as well. Justify your choice of inferential static.
Discussion section
State what your statistics mean and why you came to that conclusion
Compare your research to the research you are replicating. If there was a difference why?
Make sure to cite all the sources you used in your introduction
HL did you confirm your hypothesis?
Were there flaws in your design? explain. How would you fix those flaws next time.
